Transport Infrastructure Ireland (TII) say they have no official policy on fairies.
It comes after Kerry TD Danny Healy-Rae claimed 'The Little People' are interfering with roads.
He says fairy forts in the area are causing a dip on the main Killarney to Cork route to mysteriously re-appear.
TII say they do not have a fairy policy, but a spokesperson said it is always wise to wish The Little People the best.
"There are multiple factors involved in the deterioration of road surfaces, especially along historical national secondary routes.
"Transport Infrastructure Ireland can't offer a definitive cause for the dip in the road in Kerry without a detailed engineering investigation, therefore all potential causes remain possible", TII added.

Danny Healy-Rae's daughter has told a meeting of Killarney Municipal District Council that her father is convinced mythical creatures are interfering with the main route between Killarney and Cork.
The Irish Independent reports Maura Healy-Rae said her father is "convinced" that fairies are interfering with the road at Glenflesk, on the outskirts of Killarney.
"My father is convinced there's fairies there," Ms Healy-Rae said.
Asked if her father had seen them, Ms Healy-Rae replied: "I don't know, but he's convinced they're there".
Danny Healy-Rae is no stranger to controversy since being elected last year.
In August he said the biblical story of Noah's Ark supports the claim that climate change does not exist.
He has also compared eating a big meal and getting behind the wheel to drink-driving.
While back in July, Mr Healy-Rae told Newstalk he would be happy to get into a plane being flown by someone who had three glasses of beer.
